Embodiment 1

[0023] Embodiment 1: 100% polyester fiber new size sizing process

[0024] Fabric specification: 100% polyester yarn of Ne 45, warp density: 39.4 threads / cm, weft density: 30 threads / cm, width 170 cm.

[0025] Pulping: with a fixed volume of 900L as a unit, add 110kg of native starch, 8kg of sodium acrylic acid intermediate monomer, 2kg of wax flakes, and 50 grams of viscosity reducer sodium sulfite. First pour the raw starch into the high-pressure barrel, add 600-650L of water, heat to 118°C and stew the slurry for 30 minutes, put it into the low-pressure barrel, then add the environmentally friendly intermediate monomer and viscosity reducer, stir evenly, and control the temperature of the slurry tank at 90 -95°C range.

[0026] Sizing process: sizing tank viscosity 8.5s, sizing speed 80(m / min), sizing rate 12±1%, moisture regain 7%±1%.

Embodiment 2

[0033] Embodiment 2: T / C 65 / 35 yarn new size sizing process

[0034] Fabric specification: T / C 65 / 35 yarn of 45 British counts, warp density: 39.4 threads / cm, weft density: 30 threads / cm, width 170 cm.

[0035] Pulping: with a fixed volume of 900L as a unit, add 100kg of native starch, 6kg of potassium salt of acrylate as an intermediate monomer, 2kg of wax flakes, and 50 grams of viscosity reducer sodium silicate. First pour the original starch into the high-pressure barrel, add 600-650L of water, heat to 118°C and stew the slurry for 30 minutes, then pour it into the low-pressure barrel, then add the intermediate monomer and viscosity reducer, stir evenly, and control the temperature of the slurry tank at 90-95°C ℃ range.

[0036] Sizing process: sizing tank viscosity 8.0s, sizing speed 80(m / min), sizing rate 10%±1%, moisture regain 9%±2%.

[0043] Embodiment 3: 100% polyester fiber new size sizing process

[0044] Fabric specification: 100% polyester yarn with Ne 32, warp density: 52.4 threads / cm, weft density: 28.3 threads / cm, width 170cm.

[0045] Pulp mixing: with a fixed volume of 900L as a unit, add 112.5kg of native starch, 7kg of ammonium acrylate monomer, 2kg of wax flakes, and 50 grams of viscosity reducer (30 grams of sodium bisulfite, 20 grams of sodium sulfite). First pour the original starch into the high-pressure barrel, add 600-650L of water, heat to 118°C and stew the slurry for 30 minutes, pour it into the low-pressure barrel, then add the environmentally friendly intermediate monomer and viscosity reducer, stir evenly, and control the temperature of the slurry tank at 90 -95°C range.

[0046] Sizing process: sizing tank viscosity 8.5s, sizing speed 80(m / min), sizing rate 12±1%, moisture regain 7%±1%.

Abstract

The invention discloses slurry and a sizing process for a polyester and high-proportion polyester blended yarn, and relates to a pre-processing technology in the field of weaving, and the slurry is characterized in that the slurry comprises the following components in parts by weight: 90-110 kg of raw starch; 6-8 kg of an intermediate monomer and 0.05-0.1% of a viscosity reducer. According to theprocess, the pure starch slurry is adopted for sizing polyester fiber, and aiming at the problem that the starch slurry cannot be adhered to the polyester fiber, a proper amount of the efficient environment-friendly intermediate functional monomer and the viscosity reducer are added into the starch slurry, the functional monomer can be used for carrying out physical modification on the starch slurry, the adhesion property and the mechanical property of the functional monomer can be improved, and the starch slurry can be combined with starch, and can effectively adhere to the polyester fibers,so that the purpose of sizing the yarn is achieved; meanwhile, easy desizing is ensured.

Description

Technical field: [0001] The present invention relates to the pretreatment technology of weaving field, specifically a kind of size and sizing process of polyester and high proportion polyester blended yarn. Background technique: [0002] With the repeated improvement of product environmental protection requirements in the world, and our country has introduced a series of policies for environmental protection. my country's textile industry is facing the pressure of high cost, high energy consumption and environmental protection, and urgently needs to seek a sustainable development path that improves product quality, meets environmental protection requirements, and reduces enterprise costs. Warp sizing is a very important process in textile processing. Sizing and desizing account for 50% of the energy consumption in weaving and printing and dyeing, and the root cause is the materials used in sizing. In today's textile industry, most of them use PVA sizing that is easy to sizi...
